Connector for coaxial cable

Abstract

A coaxial cable connector having a body assembly and a cap assembly which are adapted to be secured together. The body assembly has a front body with a front body cavity formed therein, an electrically conductive collet affixed at least partially within the front body cavity, an axially moveable electrically insulative seizure bushing fitted within the front body cavity, an axially moveable mandrel fitted within the front body cavity and extending beyond said front body, and a spring fitted within the front body cavity for urging the seizure bushing towards an open position. The cap assembly has a cap body with a substantially open passage therethrough, and an outer conductor clamp fitted within the passage. The front body also has a bevelled surface proximate the open end of the front body cavity for engaging and constricting the outer conductor clamp upon joining of the body assembly to the cap assembly. The outer conductor clamp has a pusher surface for moving the mandrel from its open position towards its closed position upon joining of the body assembly to the cap assembly, thereby urging the seizure bushing towards its closed position to engage and constrict the collet.

What is claimed is: 
     
       1. A coaxial cable connector comprising: a body assembly and a cap assembly which are adapted to be secured together;   said body assembly comprising: a front body having a front body cavity formed therein, said front body cavity having at least one open end, and said front body having a first radial shoulder, and a second radial shoulder axially spaced relative to said first radial shoulder within said front body cavity;   an electrically conductive collet affixed at least partially within said front body cavity, said collet having a center conductor receiving portion which is open towards said open end of said front body cavity;   an electrically insulative seizure bushing means fitted within said front body cavity and movable from a first position towards a second position to engage and constrict said center conductor receiving portion of said collet;   a mandrel having a forward portion closely fitted within said front body cavity and a rearward portion having a smaller cross-section than said forward portion, said forward portion of said mandrel abutting said seizure bushing means, said mandrel being movable from a first position towards a second position in concert with said seizure bushing means, and said mandrel having boss means formed thereon for restricting the range of movement of said mandrel between said first radial shoulder and said second radial shoulder; and   a spring means fitted within said front body cavity for urging said seizure bushing means towards its first position;     said cap assembly comprising: a cap body having a substantially open passage therethrough; and   an outer conductor clamp fitted within said passage;     said front body having beveled surface means proximate said open end of said front body cavity for engaging and constricting said outer conductor clamp upon the joining of said body assembly to said cap assembly; and   said outer conductor clamp having pusher surface means for moving said mandrel from its first position towards its second position upon the joining of said body assembly to said cap assembly, thereby urging said seizure bushing means towards its second position to engage and constrict said center conductor receiving portion of said collet.   
     
     
       2. A coaxial cable connector comprising: a body assembly and a cap assembly which are adapted to be secured together;   said body assembly comprising: a front body having a front body cavity formed therein, said front body cavity having at least one open end, and said front body having a radial shoulder; an electrically conductive collet affixed at least partially within said front body cavity, said collet having a center conductor receiving portion which is open towards said open end of said front body cavity;   an electrically insulative seizure bushing menas fitted within said front body cavity and movable from a first position towards a second position to engage and constrict said center conductor receiving portion of said collet;   a mandrel having a forward portion closely fitted within said front body cavity and a rearward portion having a smaller cross-section than said forward portion, said forward portion of said mandrel abutting said seizure bushing means, said mandrel being movable from a first position towards a second position in concert with said seizure bushing means, and said forward portion of said mandrel abutting said radial shoulder when said mandrel is in said second position; and   a spring means fitted within said front body cavity for urging said seizure bushing means towards its first position;     said cap assembly comprising: a cap body having a substantially open passage therethrough; and   an outer conductor clamp fitted within said passage;     said front body having beveled surface means proximate said open end of said front body cavity for engaging and constricting said outer conductor clamp upon the joining of said body assembly to said cap assembly; and   said outer conductor clamp having pusher surface means for moving said mandrel from its first position towards its second position upon the joining of said body assembly to said cap assembly, thereby urging said seizure bushing means towards its second position to engage and constrict said center conductor receiving portion of said collet.   
     
     
       3. The coaxial cable connector recited in claim 1 or claim 2, wherein: said body assembly further comprises an insulator fitted within said front body cavity in a position opposite said open end, said insulator surrounding and supporting at least a portion of said collet.   
     
     
       4. The coaxial cable connector recited in claim 1 or claim 2, wherein: said cap assembly further comprises an elastomeric O-ring fitted within said passage and in alignment therewith and a clamp ring means fitted within said passage for radially compressing said outer conductor clamp upon the joining of said body assembly to said cap assembly.   
     
     
       5. The coaxial connector recited in claim 1 or claim 2, wherein: said outer conductor clamp has knurl means on its external surface for retarding rotational movement of said outer conductor clamp upon the joining of said body assembly to said cap assembly.   
     
     
       6. The coaxial connector recited in claim 1 or claim 2, wherein: the exterior surface of said front body which is adjacent said beveled surface means abuts the interior surface of said passage of said cap body upon the joining of said body assembly to said cap assembly.
